Harold Speck,Massilon, Harry L. Carr, Canton, and Ray A. Yoder, Orville, OhioApplication June 25, 1946, serial No. 679,280 11 claims. (o1. 248-354)This invention relates to an adjustable supporting device of the typeused for supporting and leveling oors of buildings.

An object of the invention is to provide adjustable supporting equipmentadapted to be utilized with readily available supporting posts such aspiping or other tubular material of varying diameters, or with solidposts such as wooden beams, whereby may be obviated the usual expenseand inconvenience of packaging, shipping or storing such posts.

Other objects of the invention will be manifest from the following briefdescription and the accompanying drawings.

Of the accompanying drawings:

Figure 1 is a vertical cross-section through adjustable supportingequipment embodying the features of the invention, the same beingillustrated in conjunction with a wooden post.

Figure 2 is a view similar to Figure 1. but illustrating the equipmentutilized in conjunction with tubular supporting posts.

Figure 3 is a top plan view on an enlarged scale and partly broken away,of an adaptor plate utilizedin the equipment of Figures 1 and 2.

Figure-4 is a front edge view of Figure 3.

Figure 6 is a front edge View of Figure 5.

Figure '7 is a top plan view, similar to Figure 3, illustrating amodified form of adaptor plate.

Figure 8 is a front edge view of Figure 7.

Figure 9 is a top plan view, similar to Figure 5, of a modified form ofbase plate or cap.

. Figure 10 is a front edge view of `Figure 9.

Referring particularly to Figures 1 to 6, the numeral I5 designates ascrew having threaded thereon a cylindrical nut I6, which is reduceddiametrically at I'I to provide an annular seat- -lng shoulder I8. Thisreduced portion of the nut Ais adapted to be slidably received either inthe end of a relatively small pipe P, indicated in chain-,dotted linesin Figure 2, with the end of the pipe in abutment with the shoulder I3of the nut, or similarly received in a central aperture I9 of an adaptorplate 20.

Adaptor plate 2Ilis suitably stamped to provide circumferentiallyspaced, inwardly projecting tangs or elements 2|, as best illustrated inFigures 3 and 4. The inner end of the screw I5 is adapted, for example,to be received in a suitable inwardly extending aperture 22 from one endof a wooden post Pa, with the adaptor plate 20 abutting the end of thepost and the projections 2l thereof embedded into the material of thepost. These elements 2I also may be utilized to maintain the adaptorplate in centered position when piping or other tubular material isutilized as indicated at P1, the elements 2| projecting either outwardlyof the wall of such tubular post (see full lines in Figure 2) orprojecting inwardly of the wall of a larger pipe (not shown).

For retaining and supporting the lower ends of the selectively availableposts a base plate 23 is provided, the same being formed from sheetmaterial with a convex central protuberance 24 which is flattened asindicated at 25 to abut the lower end of a wooden post P3. The flattenedportion 25 may have formed therein circumferentially spaced projectingelements or tangs 26, adapted to become embedded in said wooden post toretain the same in desired centered relation as shown in Figure 1. Theconvex portion of the protuberance 24 also may be utilized forsupporting in self-centering relation selectively available tubularposts of varying diameters, as indicated in full and chain-dotted linesat P1 and P, respectively, in Figure 2. The protuberance 24 is providedwith a central aperture 21 for a purpose to be described later.

The outer end of the screw I5 is provided with a head 29 apertured at 30to receive a bar (not shown) for turning the screw relatively of the nutI6, and is supported and centered by means of a cap or upper base plate28, which is simllar in all respects to the base plate 23, like partstherefore being given like numerals. Accordingly the head 29 is reducedto dene a pin 3I for reception in the central aperture of the top baseplate or cap 28, and to provide an outwardly presented annular shoulder32 for abutment with the at portion 25 of the base plate or cap. Thus,the base plate 23 and cap 28 are completely interchangeable, and eachmay be provided with apertures at 33, 33 for receiving screws 34 tosecure the same to vertically spaced members of building structures, asshown in Figures 1 and 2.

For practical application of the apparatus described, as for levelingand supporting a floor or the like, the user may be supplied with asuitable package or kit containing only a screw I5 and nut I6 thereon,two base plates 23 or 28, and an adaptor plate 20. The user then nds anysuitable post which is readily available at a hardware store, plumbingshop, or in or around the place where the work is to be done. On a farmas an example, a'wooden beam P3 of suitable crosssection and length maybe most readily acquired, and after boring or otherwise making a recessof one type of said selected post or with said convex protrusion inself-centering engagement in a recess provided in said other end ofanother type of `said selected post, said base having one or moreprojecting elements adapted to embed in the end of the first-mentionedtype of post, said mounting means including an adaptor plate forabutment with said one end of the selected post, said adaptor platehaving a central aperture, said nut having reduced portion for receptionin said central aperture of the adaptor plate and providing a shoulderfor `abutment therewith, said adaptor plate having a plurality ofdiametrically spaced projections adapted either to embed in saidrecessed end of the selected post or to serve as retaining means for theabutting end of other types of selected posts.
